What is HAART therapy for HIV?
HAART is a customized combination of different classes of medications that a physician prescribes based on such factors as the patient’s viral load (how much virus is in the blood), the particular strain of the virus, the CD4+ cell count, and other considerations (e.g., disease symptoms). Because HAART cannot rid the body of HIV, it must be taken …
What drugs are used in HAART?
Jan 20, 2007 · There are currently six classes of antiretroviral drugs able to treat HIV, each of which inhibits a specific stage in the virus's life cycle: Entry/attachment inhibitors. Non-nucleoside reverse transcriptase inhibitors (NNRTIs) Nucleoside reverse transcriptase inhibitors (NRTIs) Protease inhibitors ...
Why is it important to monitor HAART regimens?
Highly active antiretroviral therapy (HAART) for the treatment of infection with human immunodeficiency virus type 1. Highly active antiretroviral therapy (HAART) refers to a broad category of treatment regimens usually comprised of three or more antiretroviral drugs that, in previously untreated HIV-1-infected patients, are expected to reduce plasma …
What is HAART used to treat?

What drugs are used in HAART therapy?
Most HAART regimens include drugs from at least two of the three classes of antiretroviral therapy (nucleoside analog reverse transcriptase (RT) inhibitors, non-nucleoside analog RT inhibitors, and protease inhibitors).
How long is HAART given for?
Abstract. The median duration of highly active antiretroviral therapy (HAART) regimens was reported to be 11.8 months in one US study, but that study included both treatment-experienced and treatment-naive patients. The duration of initial HAART regimens for treatment-naive patients alone has not been reported.
What is HAART and what are the benefits?
HAART has revolutionized the treatment of HIV-1 disease, dramatically reducing the rate of death and the incidence of opportunistic infections as well as increasing the resolution of ongoing opportunistic infections. An additional benefit of HAART is a reduction in the use of antimicrobial agents, resulting in fewer C.
How do I know if HAART is working?
Routine Blood Testing for Effective HIV Treatment Your treatment regimen is considered effective if it's able to control HIV to the point that the virus is virtually undetectable in your body. The virus is still present, but the viral load level is low enough that HIV is considered controlled.May 22, 2014
What are the side effects of HAART?
Adverse Effects. The most common adverse effects associated with discontinuation of HAART are gastrointestinal. These commonly include anorexia, nausea, vomiting, and diarrhea. These events are usually nonspecific and may be difficult to distinguish as symptoms of the disease or adverse effects of treatment.
When do you start HAART therapy?
Accordingly, current guidelines suggest deferring therapy until later in the course of infection—that is, until the CD4+ lymphocyte count decreases to <350 cells/µL [13] or <200 cells/µL [14]. However, the optimal stage of HIV infection at which to begin therapy has not been defined.
What does HAART mean?
Drug Classes. Benefits. HAART is the acronym for "highly active antiretroviral therapy," a term coined in the late 1990s to describe the effectiveness of combination drug therapies used to treat HIV. The term is less commonly used today given that modern antiretrovirals are more than just "highly active" but able to afford people ...
How does treatment as prevention work?
The strategy, known as treatment as prevention, aims to reduce the "community viral load" within a population, making it more difficult to spread infection. 9
How do antiretrovirals work?
How Antiretrovirals Works. Antiretroviral drugs do not kill HIV; rather, they block different stages in the virus's life cycle —from the time it attaches to a cell to the time it creates new copies of itself to infect other cells.
When did protease inhibitors start?
It was with the introduction of a class of drugs called protease inhibitors in 1995 that doctors were able to combine three or more drugs in a way that stopped HIV from replicating at different stages of its life cycle. 3.
What is PREP in HIV?
The strategy, known as pre-exposure prophylaxis (PrEP), is currently recommended for people at high risk of infection, including serodiscordant (mixed-status) couples, injecting drug users, and those who engage in protected anal or vaginal sex. 13 . High vs. Low Risk Activities for HIV Transmission.
How many classes of antiretroviral drugs are there?
Today, because of improved pharmacokinetics, some antiretroviral therapies consist of only two drugs. 6. There are currently six classes of antiretroviral drugs able to treat HIV, each of which inhibits a specific stage in the virus's life cycle:
